Additional Details

The TC74VHCT574AF features a positive-edge triggered D-type flip-flop configuration. When the clock input transitions from low to high, the data at the D input is transferred to the Q output. The 3-state outputs can be disabled, allowing multiple devices to share the same bus. Key specifications include propagation delay, operating voltage range, and output drive capability. Refer to the manufacturer's datasheet for detailed electrical characteristics, timing diagrams, and package information. The device is available in a surface mount package for easy assembly.
